DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1 there is shown an assembly of building components according to one embodiment of the present invention. The assembly 10 comprises a building component 20 and an end component 40 cooperatively attached together by connector element 60. Each of the components may be formed from plastics materials such as thermoplastics such as polyvinyl chloride for example and manufactured as an extrusion or by any other suitable manufacturing process.

Building component 20 comprises a component body 21 having two spaced apart generally parallel side walls 22 and 23 with a plurality of cross walls 24 extending therebetween. Each side wall 22 and 23 comprises an inner skin 26 and an outer skin 27 with a plurality of spaced apart webs 28 therebetween. The component body 21 comprises opposed ends 31 and 32 and opposed longitudinally extending sides 34 and 35.

Building component 40 is similar in structure to component 20 in that it comprises longitudinally extending side walls 42 and 43, cross walls 44 with each side wall comprising an inner and outer skin 45 and 46 interconnected by webs 48. Building component 40 also includes an end wall 49 at one of the sides of the component body.

The assembly further includes the connector element 60 which operatively secures the building components 20, 40 together. The connector element 60 includes a main panel 62 which extends longitudinally of the components when fitted, the panel having opposed longitudinally extending edge portions 63 and 64. Spaced apart apertures 68 are formed in cross walls 24, 44 and panel 62.

The building components 20 and 40 and connector element 60 are provided with cooperating coupling elements which provide for snap fit engagement between the parts being connected. In this regard components 20 and 40 have channels 50 at each longitudinal side of the component body. Each channel 50 has a mouth 52 and formations providing for a throat 53 formed by barbed formations 54. Component 20 has channels 50 at both longitudinal sides whereas component 40 has channels 50 at the longitudinal side opposite to end wall 49. Pairs of formations are spaced along the components so that component 20 can be cut to a desired length with a coupling element being adapted for use at the cut length.

The connector element 60 comprises tongues 65 in the region of each edge portion. The tongues 65 are in the form of longitudinally extending flanges 66 having head sections 67. The arrangement is such that the heads 67 can snap fit into the channels 50 on the building components 20 and 40. Rib 79 is disposed on an outer side of the edge portion 63 and 64 so that the component edges abut the rib, so as to hold the components snugly against one another.

FIG. 6 illustrates a further embodiment of building component which is formed from a number of separate elements which can be assembled together. In this embodiment the assembly comprises two side wall members 122 and 123 which are interconnectible by a plurality of spaced apart cross members 124. Each side wall member 122 and 123 comprises an inner and outer skin 145 and 146 interconnected by webs 148. The side wall members 122 and 123 are connected together by cross members 124 which are secured to the inner skin of each side wall member. To this end the side edges of the cross-members 124 have head sections 167 which are receivable within channels 155 on the inner surfaces of the inner skins. The channels 155 have a throat section formed by barbed formations 154 on the inner surfaces of the inner and outer skins. The formations are arranged in groups which face in opposite directions, so that the component 120 may be cut to a desired length with a coupling element being adapted for use at the cut length. Typical oppositely facing groups of formations are illustrated at 157 and 158 in FIGS. 6 and 7.

Connector element 160 is of the same configuration as that described earlier, except that the head section 167 includes a void 169. End plate 168 is similar to the element 160 except that it only has one set of flanges.

FIG. 7 illustrates a corner element 170 which can connect components together at an angle relative to one another.

FIG. 9 shows a cap 75 which is installed as shown in FIG. 8 at top and bottom of the building component 20 or 120 so that, when concrete or other filler, which may include mud, sludge, sand, or the like, is poured into the component 20, 120 or 220, or 320, the concrete or other filler is inhibited from issuing and spilling onto the outside finished face of the side wall members 22 and 23. The cap has apertures 77 which allow concrete to be poured through and to mount reinforcing to key the component 20 to a floorslab 99 above and to receive key elements from below.

FIGS. 10 and 11 show another example embodiment of building component 220 wherein the connector element 260 has two flanges spaced on either side of void 269. Rib 279 is disposed on an outer side of the edge portions 263 and 264 so that components 220 abut the rib 279 when assembled, to facilitate snug or tight retention of the components 220.

FIG. 12 shows an example embodiment of another aspect of the present invention, wherein the component 320 includes cooperating coupling elements 360 integral with the sides of the sidewalls 322 and 323. A male coupling element 371 and a female coupling element 372 are provided. The male coupling element 371 includes a pair of flanges 366 spaced apart across a void 369 and a head section 367 is in the form of ribs 373. The flanges 367 are configured to insert into channel 350, through throat 353 and are retained by barbed formations 354. The engagement of the flanges 367 with the barbed formations 354 is a snap engagement.
